    摘要: Split memory cells can be provided within an alternating stack of insulating layers and word lines. At least one lower-select-gate-level electrically conductive layers and/or at least one upper-select-level electrically conductive layers without a split memory cell configuration can be provided by limiting the levels of separator insulator structures within the levels of the word lines. At least one etch stop layer can be formed above at least one lower-select-gate-level spacer material layer. An alternating stack of insulating layers and spacer material layers is formed over the at least one etch stop layer. Separator insulator structures are formed through the alternating stack employing the etch stop layer as a stopping structure. Upper-select-level spacer material layers can be subsequently formed. The spacer material layers and the select level material layers are formed as, or replaced with, electrically conductive layers.

    摘要: An alternating stack of sacrificial material layers and insulating layers is formed over a substrate. Replacement of sacrificial material layers with electrically conductive layers can be performed employing a subset of openings. A predominant subset of the openings is employed to form memory stack structures therein. A minor subset of the openings is employed as access openings for introducing an etchant to remove the sacrificial material layers to form lateral recesses and to provide a reactant for depositing electrically conductive layers in the lateral recesses. By distributing the access openings across the entirety of the openings and eliminating the need to employ backside trenches for replacement of the sacrificial material layers, the size and lateral extent of backside trenches can be reduced to a level sufficient to accommodate only backside contact via structures.

A source conductive line structure is provided between the substrate and the alternating stack. The source conductive line structure includes a plurality of parallel conductive rail structures extending along a same horizontal direction and adjoined to a common conductive straddling structure. Each memory stack structure straddles a vertical interface between a conductive rail structure and a support matrix. A semiconductor channel in each memory stack structure contacts a respective conductive rail structure and the support matrix.
